n. CALCULATING MACHINE.

Application led February 29, 1924, Serial No. 695,983, and inl Germany March 7, 1923.

My invention relates to improvements in Referring first to the construction of 55 calculating machines, and more particularly Flgs. 1 and 2, a calculating machine in which to those machines of the type in which the my invention may. be embodied is shown setting disks of a setting mechanism are each `which consists of setting disks l each having provided with nine teeth adapted to be nine equidistantly spaced radial teeth 2 shifted in radial direction by cam disks .mounted thereon, cam disks 3 adapted to 60 which are rotatable-for transmitting values shift the teeth 2 outwardly and into operset thereon to the numeral wheels of the regative position, transmission gears 4 operable istering mechanism by means of transmisto transmit the values set on the setting disks 0 sion gears. In' machines of this type means to numeral wheels 5, resetting means for the have been provided for carrying the values numeral wheels in the nature of a wing 65 from the registering mechanism to the setnut 6, a bracket or slide 7 carrying the ting mechanism consisting of gears connectnumeral wheels 5, a latch lever 8 rockingly ed with the individual cam disks and adaptmounted on the slide 7 and adapted for ened to be operated by the said transmission gagement with either one of slots 9, 10 gears after shifting a slide which carries the formed in the base plate 11, and gearsl l2 on 70 registering mechanism and the transmission the cam disks 3. The slide 7 is adapted to gears into position for engagement with the be shifted relatively tothe 'setting mechagears of the cam disks. For fixing the slide nism or disks for bringing the numeral in the proper positions additional slots must wheels 5 into position for receiving the be provided in the guide ofthe slide, which values from any of the setting disks, or for 75 is objectionable because the base plate is transmitting the values from the numeral weakened and the setting of the slide in the wheels to the setting disks, and it is adapted proper positions is rendered diflicult. to be secured in any of its positions by en- An object of the improvements is to pro-- gagement of the lever 8 with the correspondvide a machine of the class referred to in ing slot .9 or 10. 80

values set thereon to the cam disks, so that, when operating the resetting mechanism, the

vvalues are carried from the numeral wheels to the cam disks and through the latter to the setting disks.

For securing the bar b in the normal position shown in Fig. 3 and corresponding to the transmission of values from the setting disks to the registering mechanism, a slidable bolt e is provided which is urged toward bar b by a spring f. Said bolt may be retracted to permit the bar I) to be shifted by means of a bell-crank lever g into the position corresponding to the transmission of values from the numeral wheels to the settingdisks. rlihe bell-crank lever g\is fulcrumed at g to the frame of the machine and connected at g2 to the bar 6. In Figs. 3 and 5 I have shown preferred means for actuating the bolt e and the bell crank lever g comprising a rod having an operating-,key

n thereon. Said rod h is vertically movable' in suitable guides o formed in the machine frame and near its lower or inner end has an inclined slot h1 engaged by a pin e1 secured to lthe bolt e. After the bolt e has been moved out of locking engagement with the I' .bar b the rear end of the bolt e strikes l tached to thebell crank lever g urges said lever and the bar b into initial position, whereupon the bolt e ismmoved into locking engagement with the barb by the spring f.
